Definitions
- the invention relates to a length-adjustable gas spring after the top handle of claim 1.
- a length-adjustable gas spring after the top handle of claim 1.
- EP 0 789 157 A corresponding US Ser. No. 08/797 627
- known length-adjustable gas spring has a pneumatic release device or a mechanical on train and Pressure release device on. Both tripping devices are relatively expensive.
- the invention is therefore based on the object of the gas spring of the generic type Kind with a release device to be provided in their Construction is particularly simple and easy to use.
- the Bowden cable is a particularly simple one and robust component. To open the valve only one Force applied in one direction; the provision is made in the Usually by the internal forces acting on the operating lever.
- the Sub-claims give particularly advantageous and partly inventive Refinements again.
- the training according to claim 6 enables it that the trigger device with the actuator as an independent Component can be manufactured.
- a length-adjustable gas spring is shown, as it is known is. It has a housing 1, which consists essentially of two concentrically nested pipes with different diameters, namely an inner cylinder 2 and an outer cylinder 3. Between the outer cylinder 3 and the inner cylinder 2 is due to the different Diameter of inner cylinder 2 and outer cylinder 3 an annular space 4 is formed.
- An approximately annular piston 5 is axially displaceable in the inner cylinder 2 arranged, the gas-tight via a sealing ring 6 with its outer circumference sealed against the inner wall 7 of the inner cylinder 2 is.
- the piston 5 is guided coaxially in the housing 1 at one end Piston rod 8 attached. This piston rod 8 is from one end of the Housing 1 led out sealed.
- the piston 5 divides the interior of the inner cylinder 2 in two part housing spaces 9, 10.
- the piston rod outlet facing part housing space 9 is constantly with the annulus 4 via a connection opening, not shown in the drawing connected.
- the one outer section 14 associated ring seal 18 is by a the outer section 14 attached pot-shaped outer lid 20 of the Valve body 13 held.
- the one assigned to the inner section 15 Ring seal 19 is by a placed on the inner portion 15, the inner housing 21 of the valve body facing the partial housing space 10 13 held.
- the valve body 13 and the cover 20, 21 are in usually made of a suitable plastic and are made by gluing, ultrasonic welding or press, snap or snap connections with each other connected.
- a release device 41 for the valve actuation lever is in the spacer sleeve 40 24 used. It has a housing 42, which by means of a polygonal tube 43 rotatably and by locking in the direction of Axis 12 is held in the spacer sleeve 40. It still shows a flat plate-like section 44, which is integral with the polygonal tube 43 is formed and rests against the edge 39. In the housing section 44 is - as can be seen in FIGS. 3 and 5 - a holder 45 for the outer tube 46 of a Bowden cable 47, in which the outer tube 46 is held immovably in its longitudinal direction.
- This slidable bearing piece 55 is with an operating button 56 connected via a web 57 which overlaps the bearing piece 53.
- the outer tube 46 is relative to the sleeve 52 moved into the position shown in Figure 4; relative to the outer hose 46, the wire pull 50 is thus in the direction of the actuating device 51 moved.
- the valve 11 is opened.
- the actuation button 56 is reset, for example supported by a spring, not shown, in the actuating device 51 could be.
- the length-adjustable gas spring at least partially filled with compressed gas is used in a generally conventional manner such that the tapered Fastening section 38 in a holding device only indicated 59 attached to the underside of a chair seat by cone clamping and that otherwise the housing of the gas spring on a not shown Guide bushing of a standpipe connected to a base frame Slidable in the direction of the axis 12, but arranged transversely to it becomes.
- the piston rod 8 is on a bottom of such a standpipe rotatably attached. This configuration is very general practice.
